MECHANICAL MOVEMENT.

Application filed. March 17, 1908. Serial lrlo. 521;389.

To all whom tt may cyacem:

Be it known that l, BYRON Hose, a citizen of the United States, residing at Palermo, in the county of Butte and State of California, have invented a new and useful Mechanical Movement, of which the following is a specifi cation in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a device is used for the purpose of changing a rotary motion 0f.any shaft or other power generating deviceinto a reciprocatoryrnotion, where it is necessary tohave the stroke lon er than would be advisab'leJto have it were t 1e ordinary eccentric pin used to convert the inotion from rotary to reciprocatory.

This device is used for the purpose of changing the motion of windmills to reciprocatory where the stroke is quite long, or in. a'nyother place where the stroke may be desired to be made diderent atdilierent times, the change in the length of stroke bein easily made by simply moving one oi the sprocket wheels closer to the other and takin out some of the links of the chain used.

n the drawing, in which the same numeral of' reference is applied to the same parts throughout, Figure 1 is a side elevation of the device With some of the parts shown in section, F ig. 2 is a plan view of the device with the guides shown in section, and Fig. 3 is an end elevation of the device looking in the direction of the arrow in Fig. 1.

The numeral 1 represents a pitnian which may be connected with any desired machinery where a reciprocating motion is desired. To the pitman is secured a head 2 which has the arms 3 and 4 connectedtherewith. Each of the arms 3 and 4 is provided with a forked end having fingers 5 and 6 those on the arm 3 depending from the arm and those on the arm 4 projecting u wardly. The arms operate through a mi e 7 said guide having the channels 8 and 9 to guide the rollers of the chains 10. The chain which drives the arms passes over the sprocket wheels J1 and 32 one or both of which may be used for the generation of the power used. The chain is provided with the pin 13 whichlias a roller 14 on each side of the same, the rollers being long enough to project across the fingers 5 and 6 of the arms far enough to pass into the slots at the sides of the guides; served that each'set of fingers is just long It will be obenough to hold the rollers securely and yet at the same time pass over the shatt of the adjacent sprocket wheel. a

The operation of the device is as follows: The chain is moved in the direction of the so arrow by the rotation of the sprocket wheels, the rollers being carried along Filth the chain and pushing the arm to the position indicated in the drawing. The chain continues to travel it goes forward the rollers (in pass off the arm 3 and pass down to the inner side of the upwardly extending fingers on the arm. 4 and as the chain continues its travel the arm is drawn to the other end of the guide, where the chain causes, the pins to rise up away from the lower set of fingers and pass in front of the upper set of fingers again thus pushing the pitrnan hack to the original position.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is as follows, modifications Within the scope of the claims being reserved.

1. In a mechanical movement, the corn hination of a pair of sprockets spaced a distance apart on parallel shafts, a sprocket chain passing over the wheels, a pin carried by the chain and having a roller on each side thereof, a pitnian, two arms connected with 8 l than each arm having a pair of lingers the lingers oi one arm being in advance of the fing rs on the other arm, and a guide for the a-.ns and rollers.

2. a mechanicalmovement, the combination f a finale having a uide slot on each side tl if, a pair of sprocket Wheels spaced adistar wpurt on parallel shafts, a sprocket chain pa ng over the wheels, a pin carried by the cln and having rollers on each side thereof, p man adapted to he reciprocated through the frame, arms connected with the pitinan and adapted to he directed by the frame, and two iin 'e'rs depending from and extending above t 1e resnective arms and adapted to he carried back and forth by the 1"ollers on the chain.

In testimony whereof I have set. my hand this 3rd day of March A. D. 1908, in the presence of the two subscribing witnesses.

BYRON HUSE.
